2. Kev Txawj Ntse: Txhim kho Synaptic Plasticity thiab Kev Ua Haujlwm Nco
Lub hom phiaj ntawm kev txawj ntse poob qis thiab kev kawm-kev nco tsis zoo, cov tshuaj peptide ua los ntawm kev tswj cov neurotransmitters thiab cov qauv synaptic.
Synaptic txhim kho los ntawm nootropic peptides
Qee cov peptides (piv txwv li, Sema) ua raws li kev ua haujlwm ntawm thyrotropin-tso cov tshuaj hormones, txhawb kev tso tawm ntawm dopamine thiab norepinephrine. Qhov no txhim kho synaptic plasticity nyob rau hauv hippocampus, txhim kho spatial nco nyob rau hauv Alzheimer tus kab mob qauv. Cov kev tshawb fawb soj ntsuam pom tau hais tias lawv tuaj yeem txhawb cov qhab-nees kev txawj ntse thiab kev ua cov ntaub ntawv ceev.
Cholinergic system tswj
Qee cov cholinergic-mimicking peptides txhim kho acetylcholine kev sib kis tau zoo thiab txhim kho choline concentration hauv synaptic clefts, tuav lub peev xwm rau kev cuam tshuam rau kev puas hlwb me me thiab kev txawj ntse tom qab poob.
Anti-amyloid deposition:
Aβ-targeting sequences (piv txwv li, peptide ntu 176-191) inhibit Aβ fibril aggregation, txo qhov tsim ntawm neurotoxic plaques thiab ncua kev pathological ntawm Alzheimer's kab mob, ua rau lawv tshawb fawb hotspot rau kev cuam tshuam ntxov.
3. Kev Tswj Xyuas Kev Nyuaj Siab: Reshaping Neurotransmitter Balance thiab Stress Response
Cov tshuaj Peptide cuam tshuam hauv kev xav tsis zoo xws li kev ntxhov siab thiab kev nyuaj siab los ntawm kev ua haujlwm ntawm limbic system thiab neuroendocrine axis.
5-HT txoj kev hloov kho
Qee cov peptides (piv txwv li, Sel), raws li qhov zoo modulators ntawm GABA_A receptors, txhim khu γ-aminobutyric acid (GABA) inhibitory kis tau tus mob, sai alleviating cov tsos mob ntawm kev ntxhov siab vim. Lawv qhov pib ceev thiab kev nyab xeeb profile tshaj cov tshuaj benzodiazepines. Tachykinin receptor antagonist peptides txhim kho anhedonia hauv kev nyuaj siab los ntawm inhibiting P tso tawm.
HPA axis tswj
Peptides xws li oxytocin txhim kho prefrontal cortical kev cai ntawm amygdala, txo kev ntxhov siab hormone cortisol qib. Qhov no txhim kho kev nco txog kev xav hauv kev ntxhov siab thiab kev ntxhov siab tom qab (PTSD).
Neuroplasticity kho
